Title:
ペーパーマシンにおける方法及びシステム並びにソフトウェア
Document Type and Number:
Japanese Patent JP4629109
Kind Code:
B2
Abstract:
The invention relates to a method and system for a paper machine comprising calculating the heat recovery heat flow Q rec , the heat flow Q pw required for heating the process water, the heat flow Q MR required for heating the ventilation air of machine room ventilation, Q sup required for heating the supply air of the dryer section and the evaporation amount m ev of the dryer section. Also the dimensioned evaporation amount in the dyer section m ev, dim is determined and the values are used for calculating the heat recovery efficiency EFF rec by the formula: EFF rec = (Q rec /(Q pw + Q MR + Q sup ))*(m ev, dim /m ev ). The invention relates also product comprising program code elements disposed to perform the steps of the method.
